SX1000 includes large amount of flat unsleeved cables. The 24-PIN cable is proprietary and includes sense cable/connector. Each of the three 8-PIN PCIe cables splits off into dual 6+2-PIN connectors.
TESTING
We used the following hardware for testing in 20°C ambient temperature.
| CASE | Open Testbench |
| MOTHERBOARD | Rog Strix B660-I Gaming WiFi |
| CPU | Intel 12700K (paid link) |
| GPU | RX 6900XT (paid link) |
| PSU | SilverStone SX1000 (paid link) |
| RAM | 32GB DDR5 (2x16GB), 6000MHz (paid link) |
NOISE
The SX1000 features 0RPM upto 300W and outputs between 20~25dB(A) noise upto 700W. The stock fan produces noticable motor noise which is audible alongside the fan noise between 300~700W range. Noise output substantially increases above 700W with max output of 45dB(A) at 1000W. Noise testing data sourced from Cybenetics.
TEARDOWN
The SilverStone SX1000 (v1.1) uses 120x15mm Globe Fan at 12v, 0.45amp (model: B1201512HB) with 2-PIN mini fan header. Mainstream fans from Noctua, Thermalright, Scythe, ARCTIC etc will not spin up when paired with the SilverStone SX1000 due to lower ampage. This means fan replacement for the SilverStone SX1000 will be difficult as 120x15mm fans using 0.45amp are very uncommon and will likely be lower quality than the included fan and therefore pointless.
